Construction method for structure

Abstract

A construction method of a structure provided with a lower structure part entirely arranged below a ground surface and an upper structure part at least a part of which is arranged below the ground surface on the lower structure part, the construction method including a step of constructing the lower structure part below the ground surface, a step of allowing a heavy object to travel on a travel route including a range that affects the lower structure part after the lower structure part is constructed, and a step of constructing the upper structure part on the lower structure part after the heavy object is allowed to travel.

1 . A construction method of a structure provided with a lower structure part entirely arranged below a ground surface and an upper structure part at least a part of which is arranged below the ground surface on the lower structure part, the construction method comprising:
 a step of constructing the lower structure part below the ground surface;   a step of allowing a heavy object to travel on a travel route including a range that affects the lower structure part after the lower structure part is constructed; and   a step of constructing the upper structure part on the lower structure part after the heavy object is allowed to travel.   
     
     
         2 . The construction method for a structure according to  claim 1 , wherein
 the travel route is temporarily provided after the lower structure part is constructed, and the travel route is removed before the upper structure part is constructed.   
     
     
         3 . The construction method for a structure according to  claim 2 , wherein
 the travel route is temporarily provided by backfilling the lower structure part.   
     
     
         4 . The construction method for a structure according to  claim 1 , wherein
 a part of the upper structure part is constructed so as to protrude to a ground.   
     
     
         5 . The construction method for a structure according to  claim 1 , wherein
 the structure is a foundation provided with a footing serving as the lower structure part and a pedestal serving as the upper structure part, and   at the step of constructing the lower structure part, the footing is constructed so as to include a reinforcing bar joined to the pedestal.   
     
     
         6 . The construction method for a structure according to  claim 5 , wherein
 at the step of constructing the lower structure part, the footing is constructed so as to include at least a part of a mechanical joint, and   at the step of constructing the upper structure part, the pedestal is constructed so as to include a reinforcing bar joined to the footing, and the reinforcing bar of the footing and the reinforcing bar of the pedestal are joined to each other using the mechanical joint.   
     
     
         7 . The construction method of a structure according to  claim 1 , wherein
 the structure includes a cavity in the structure,   at the step of constructing the lower structure part, construction is performed in such a manner that the cavity opens upward, and a temporary lid is further installed in the cavity, and   at the step of constructing the upper structure part, the temporary lid is removed.
